Abstract
A narrow self-propelled trench soil compactor has a vibratory frame assembly connected in a towing relation to a mobile frame having steerable front wheels. The vibratory frame assembly is pivotally connected to the mobile frame for vibratory up and down movement independently of the mobile frame. A soil compaction wheel is rotatably supported at the free end of the frame assembly for movement to a lowered operating position and is power driven to function as the propulsion means for the machine. When the compaction wheel is in an elevated or non-operating position, the machine is attachable to a towing tractor for transportation purposes.
Claims5
A narrow trench soil compactor comprising:
- (a) a self-propelled mobile unit with a main frame having a pair of transversely opposite rear wheels and steerable front wheels and a wheel base of about six feet;
- (b) a vibratory frame assembly, including a shaker unit and a rotatable soil compacting wheel;
- (c) means pivotally connecting the vibratory frame assembly to the main frame for up and down vibratory movement of said soil compacting wheel between said rear wheels;
- (d) primary power means on the main frame for driving said soil compacting wheel to propel said mobile unit;
- (e) secondary power means on the vibratory frame assembly for driving said soil compacting wheel to propel said mobile unit;
- and
- (f) means providing for a free floating pivotal movement of the vibratory frame assembly whereby the compaction wheel is permitted to follow the contour of the soil at the bottom of the trench.
